+Zynq Watchdog Device Tree Bindings
+-------------------------------------------
+
+Required properties:
+- compatible		: Should be "cdns,wdt-r1p2".
+- clocks		: Input clock specifier. This should be the ref clk.
+- reg			: Physical base address and size of WDT registers map.
+- interrupts		: Property with a value describing the interrupt
+			  number. This interrupt is used for indication
+			  when the watchdog times out.
+- interrupt-parent	: Must be core interrupt controller.
+
+Optional properties
+- reset			: If this property exists, then a reset is done
+			  when watchdog times out.
+- timeout-sec		: Watchdog timeout value (in seconds).
+
+Example:
+	watchdog@...05000 {
+		compatible = "xlnx,zynq-wdt-r1p2";
+		clocks = <&clkc 45>;
+		interrupt-parent = <&intc>;
+		interrupts = <0 9 1>;
+		reg = <0xf8005000 0x1000>;
+		reset;
+		timeout-sec = <10>;
+	};
